From 53375a5a218e7ea0ac18087946b5391f749b764f Mon Sep 17 00:00:00 2001 From: Peter Zijlstra Date: Mon, 15 Mar 2021 17:12:53 +0100 Subject: x86/cpu: Resort and comment Intel models The INTEL_FAM6 list has become a mess again. Try and bring some sanity back into it. Where previously we had one microarch per year and a number of SKUs within that, this no longer seems to be the case. We now get different uarch names that share a 'core' design. Add the core name starting at skylake and reorder to keep the cores in chronological order. Furthermore, Intel marketed the names {Amber, Coffee, Whiskey} Lake, but those are in fact steppings of Kaby Lake, add comments for them.
